Answer:

The correct option is C.  

Step-by-step explanation:

Given that Carlos operates a helicopter. Carlos decides to measure the rotational velocity of the helicopter blades. we have to find the appropriate unit for Carlos's purpose.

The angular velocity ω is the rate of change of angle with respect to time,

The formula to find the rotational velocity is

\text{Rotational velocity}=\frac{d\phi}{dt}

Angle measure in radians or degrees and time in second.

Hence, the appropriate unit for Carlos's purpose is degrees per second.

The correct option is C.

Marta_Voda [28]

Bonjour,

Soit c le côté de l' hexagone.

On a 5.2²+(c/2)²=c²

==>c²=5.2*4/3

c²=104/15

c=√(104/15)=2,6331223544175332023251281391631...

Aire de l'hexagone= 5.2*c/2*6=41,076708728913517956271998970944

Je me suis permis de répondre en Français car l'énoncé était en Espagnol. (Thanks to Google translator)

Jarred sells DVDs. His inventory shows that he has a total of 3,500 DVDs. He has 2,342 more contemporary titles than classic tit
GaryK [48]
Answer: x = 2921, y = 579

Step-by-Step Explanation:

I am assuming that we just have to Solve for ‘x’ and ‘y’.

‘x’ = No. Of Contemporary Titles
‘y’ = No. Of Classic Titles

=> x + y = 3500 (Eq. 1)
=> x - y = 2342 (Eq. 2)

Adding Eq. 1 and Eq. 2, we get :-

2x = 3500 + 2342
2x = 5842
x = 5842/2
=> x = 2921

Therefore, x = 2921

Substitute value of ‘x’ in Eq. 1 :-

x + y = 3500
(2921) + y = 3500
y = 3500 - 2921
=> y = 579

Therefore, y = 579

Hence,
No. Of Contemporary Titles = 2921
No. Of Classic Titles = 579

Find thhe remainder when 7^203 is divided by 4
Aleksandr [31]
Using the square-and-multiply approach, we have

7^{203}=7\times(7^{101})^2
7^{101}=7\times(7^{50})^2
7^{50}=(7^{25})^2
7^{25}=7\times(7^{12})^2
7^{12}=(7^6)^2
7^6=(7^3)^2
7^3=7\times7^2

and so, using the property that, if a_1\equiv b_1\mod n and a_2\equiv b_2\mod n, then a_1a_2\equiv b_1b_2\mod n, we get

7\equiv3\mod4
7^2\equiv9\equiv1\mod4
7^3\equiv7\times1\equiv7\equiv3\mod4
7^6\equiv9\equiv1\mod4
7^{12}\equiv1\mod4
7^{25}\equiv7\times1\equiv7\equiv3\mod4
7^{50}\equiv9\equiv1\mod4
7^{101}\equiv7\times1\equiv7\equiv3\mod4
7^{203}\equiv7\times9\equiv3\times1\equiv3\mod4
